Am I doing something wrong?

Recently, snapping off the shutter release does: nothing. Wait, click, release. Or, unscrew lens; all completely inconsistent! Dang that electronic crud! What am I doing wrong? 17-40L.... shouldn't be this way, no?

Thanks!
 
Recently, so that means at one time it did work? If so, what has changed since then?

Is it absolutely nothing? you don't have MLU on, long exposure or anything like that do you? Is the battery dead? Have you removed both batteries to reboot?
 
Will it work in manual focus mode?
Try it, if you havnt already.

Sometimes in autofocus the shutter will not release if it does not have focus lock.

Well, I think the best solution is reading the answers of similar problem given to other member may help. I just read the very similar problem and it got some responses there.

I don't know what 17-40L has anything to do to cause the problem... and my suggestion is to check the F-STOP and camera setting. And may be little extra information of the lighting situation at your end would cut down some wild guesses.

Heck, I am not even sure if you read or following this threat ;)
 
Yes. Sorry, passed out last night :)

Simply, I'd press the shutter, nothing. Late afternoon and evening. Wait. Press shutter, works. Completely inconsistent. It's like the camera just doesn't want to work. Lots of battery. Turn off/on. Doesn't work, try again, nope. Try again, works.

It doesn't lock up, it simply doesn't work. Weird.

Hold on.

I just tried shooting without AF, it's totally fine. I remember using the AF Multi-controller for a focus point last night (possibly that afternoon too), and for some reason, the AF indicator is "stuck" on one point. I mean, I can move it, but it stays on the selected point. What mode is this, and how do I get back to "normal" AF?

See, this is why I hate AF. :)
 
First... what are your settings?

I assume that you have it on one-shot focus? In that case the camera will not fire until it finds focus. So I don't think that it is so random after all.

As for your problem with selecting AF point. What is C.Fn13 set to? It changes the behaviour of the multi controller.

BTW: I know that you've written that you've read the manual, but I am somewhat doubtful... page 77 describes how to change AF point
 
I did. I reread it. I'm bad with comprehension. I get it now.

I think once you use the multi-controller, it stays on that focus point, so yes, it was not random. This is one of those times where technology gets in the way (for me).

Now that I know, I know to press the [+] right-thumb button after doing a selective AF point with the multi-controller. I wish the viewfinder display wouldn't sleep so fast though.
 
On several occasions by new 30D has not obeyed me properly. However, being from a computer background, my first thought is 'How have I sinned'? If I assume it's MY fault, I usually get better results than damning the gods. In every case so far - including a VERY confusing session when shooting macro, cured when I figured out my subject flower was too close to focus properly (BAAAD flower!) - the camera was right and I was wrong.
 
I' want control over when the camera fires. I'd rather have a slightly out of focus shot than no shot at all.

I like the single shot AF mode generally, but there are times when it's just so darn frustrating to have the camera refuse to take a shot because IT thinks I don't have things in focus. How dare it!!!! I am the master, darn it!

So I tend to use a lot of manual focus. Then the camera fires when I press the button :)

It should have a "sloppy" mode where it'd go ahead and take the photo even against it's better judgment as long as you'd had the button half-pressed for long enough that it should have been able to get AF lock.

I can see it holding back for a short while if it's in AF and you just mash the button down all at once. After all, it's got to give the lens a little time to do it's part in the AF scheme.

But if I've got that button on half press, the darn thing better fire when I press it fully, and right now!

Manual is often the answer in these situations :)

Then it reassesses the focus on its own. I want to half-press to lock focus, then have it fire when I full press - and I mean RIGHT when I full press. But I dont' want it trying to track anything :)

I did see the ;) too, though so I know what you meant.

Maybe some folks would say that all of the AF modes are "sloppy" :)

By the way, have you ever looked at the word "reassesses" before? Seeing it up there on the screen, it just doesn't look "right" does it?
